Adif, the Spanish railway infrastructure manager, has announced a new EUR 10.7 million contract for technical assistance in constructing the first section of the Burgos–Vitoria High-Speed Line (LAV), reinforcing its commitment to enhancing Spain’s national rail network.
The tender covers construction supervision for the Pancorbo–Ameyugo section of the route, which spans 8.4 km and is currently also open for construction bids. The scope of the contract includes comprehensive support for site management and oversight to ensure technical, environmental, economic, and quality compliance.
The platform layout presents a significant technical and engineering challenge, with 77% of the route running through three tunnels and three viaducts. Among the key features are the 4 km Pancorbo Tunnel, which passes through the Montes Obarenes Natural Park, and a 1.1 km viaduct spanning the NI and SC-BU-7 roads and the Arroyo de la Llosa stream.
Adif has already tendered the construction of this section with an estimated value of EUR 439 million and is progressing with project planning for the remaining segments of the line, with the goal of tendering all works by 2026.
The Burgos–Vitoria LAV is a strategic infrastructure project designed to connect the Basque Country to Spain’s wider high-speed rail network. It includes a double-track standard-gauge alignment and a single-track bypass at Miranda de Ebro, enabling high-speed trains to call at the town without passing through its centre.
Once complete, the line will link with the Madrid–Valladolid–Burgos high-speed route, providing direct connections to the Basque capitals and onwards to the French border. The project is also a major development within the Atlantic Corridor, supporting improved mobility, economic growth, and regional cohesion.
This initiative contributes to several of the United Nations Sustainable Development Goals (SDGs), including SDG 9 (industry, innovation and infrastructure), SDG 7 (affordable and clean energy), and SDG 8 (decent work and economic growth).
The project may be co-financed through the European Union’s Connecting Europe Facility (CEF), which supports trans-European transport infrastructure development.
